Description

  The present invention relates to unit dose products that release liquid fabric treatment compositions. In particular, the present invention relates to a single-compartment sachet non-aqueous composition that provides the fabric cleaning and fabric softening benefits afforded by an easy-to-handle unit dose system.

  Fabric cleaning / softening products are supplied in many forms such as granules, liquids, tablets, and sachets. Each form has its own advantages and disadvantages.

  In recent years, water-soluble sachets containing fabric cleaning or softening actives have become widespread. In general, a sachet comprises a water-insoluble liquid composition surrounded by a water-soluble film such as a polyvinyl alcohol film. Such products have the advantage that they are convenient to divide into appropriate amounts, are easy to handle and hardly foul when compared to conventional composition forms. EP 339707 (Unilever) discloses a non-aqueous detergent composition contained in a PVA film. PCT International Publication No. WO 01/81520 (Colgate) discloses a wash cycle single compartment unit dose softener composition.

  However, neither of these two approaches provides both a cleaning effect and a softening effect at the same time. PCT International Publication No. WO 01/85888 discloses a unit dose composition that provides a fabric softening effect and contains no more than 5% by weight of a surfactant. The disadvantage of this system is the low cleaning performance due to the low content of surfactant.

  The prior art also provides a unit dose system, which simultaneously provides a fabric cleaning effect and a fabric softening effect. However, due to the compatibility issues of cleaning systems containing anionic surfactants and fabric softening systems containing cationic fabric softening actives, PCT International Publication No. WO 02/08380 (P & G) This approach relates to a double-compartment sachet in which the first compartment contains a detergent composition and the second compartment contains a fabric softening composition.

  It is well known in the art that dual compartment unit dose systems are not easy to manufacture and are not particularly easy in an economical manner. Accordingly, it is an object of the present invention to provide a single compartment unit dose non-aqueous liquid fabric treatment composition which provides superior performance in terms of cleaning and fabric softening effects.

  To achieve this goal, it is necessary to overcome the incompatibility issues between anionic surfactants and fabric softening actives, especially when the fabric softening active is a cationic fabric softening active. There is. The present invention provides a solution to this problem through the use of non-cationic fabric softening actives that can be combined with anionic surfactants and do not cause incompatibility problems.

  Another problem associated with incorporating a cationic softener into a water-soluble film is the interaction of the cationic softener with the typically negatively charged surface of the polyvinyl alcohol-containing film. This difficulty has also been overcome by the use of non-cationic fabric softening actives that can be combined with negatively charged film surfaces and do not cause incompatibility problems.

  Furthermore, prior art unit dose products have drawbacks with respect to rapid and complete dissolution upon contact with water. Therefore, another object of the present invention is to provide a sachet composition that can be quickly and completely disassembled so as not to leave excessive residue in the drawer, laundry drum, or washed clothes. is there.

  Surprisingly, it has now been found that the sachet compositions of the present invention demonstrate very good cleaning performance and very good fabric softening performance, in particular softening performance. In addition, it has been found that the sachet compositions of the present invention demonstrate better solubility and / or lower residue formation.

The present invention relates to unit dose products in the form of liquid fabric treatment compositions contained in single compartment water soluble sachets. The inner space of each sachet
(A) a cleaning system comprising at least one anionic surfactant in excess of 5% by weight of the fabric treatment composition; and (B) comprising fabric softening clays, fabric softening silicones, and mixtures thereof. A fabric softening system comprising at least one non-cationic fabric softening active selected from the group;
Fabric softening clay is added as a premix containing clay and solvent; fabric softening silicone is added as a premix containing silicone and solvent, or fabric softening silicone as a pure compound without solvent Added.

  Water-soluble sachets are typically in direct contact with the composition.

  The process for producing the unit dose product of the present invention and the use of the unit dose product of the present invention for treating fabric through a single compartment water soluble sachet and thus imparting a fabric cleaning effect and fabric softening effect is also the present invention. The theme of The method for producing a unit dose product herein relates to separately preparing a fabric cleaning system and a fabric softening system and then combining the two systems.

  The sachets herein are typically closed structures that enclose the volumetric space and are made of the materials described herein. The sachet contains a fabric treatment composition, which can be in any suitable form as long as the composition is at least partially liquid. The composition must include a fabric cleaning system and a fabric softening system. In the following, these elements will be described in more detail.

  The sachet and its volume space may be any form, shape and material suitable for holding the composition, for example, during washing, to prevent the sachet from releasing the composition before it comes into contact with water. Can be. The exact approach depends, for example, on the type and amount of the composition in the sachet, the nature required for the sachet to hold, protect and deliver or release the composition as long as the sachet is a single compartment water soluble sachet. Is done. Preferably, the pouch has a spherical shape.

  The sachet contains a unit dose of the composition herein suitable for the required operation, for example, a single wash, or the amount used depending on, for example, the size and / or degree of soiling of the laundry. May be sized to simply contain only a partial dose that gives the consumer greater flexibility.

(1, single compartment water-soluble sachet)
The pouch is typically made from a water-soluble film. Preferred water soluble films are polymeric materials, preferably polymers formed into films. The material in the form of a film is obtained by methods known in the art, for example by polymer material casting, blow molding, extrusion or blow extrusion.

The water-soluble film used herein is typically at least 50%, preferably at least 75%, or even at least as measured by the method shown below using a glass filter with a maximum pore size of 50 μm. It has a solubility of 95%. That is,
The gravimetric method for determining the water solubility of the compartment and / or sachet material is as follows.

  Add 50 g ± 0.1 g of material to a 400 ml beaker, weigh it and add 245 ml ± 1 ml of distilled water. This is vigorously stirred for 30 minutes with a magnetic stirrer set at 600 rpm. The mixture is then filtered through a prefabricated qualitative glass filter having a pore size as defined above (up to 50 μm). Water is dried from the collected filtrate by any conventional method and the weight of the remaining polymer is measured (this is the dissolved or dispersed fraction). Thereafter, the rate of solubility or dispersibility can be calculated.

  The water-soluble film and preferably the sachet as a whole may be preferably stretched during sachet formation and / or upon closure so that the resulting sachet is at least partially stretched. This is to reduce the amount of film needed to confine the pouch volume. As the film is stretched, the thickness of the film decreases. The degree of stretching indicates the amount of stretching of the film by reducing the thickness of the film. For example, if the thickness of the film is exactly halved by stretching the film, then the stretched degree of the stretched film is 100%. Also, if the film is stretched so that the film thickness of the stretched film is exactly one-fourth that of the unstretched film, the degree of stretching is exactly 200%. Usually and preferably, the thickness, and thus the degree of stretching, is non-uniform throughout the pouch due to the forming and closing method.

  Another advantage of stretching the pouch is that when forming the pouch shape and / or closing the pouch, the stretching action stretches the pouch unevenly, resulting in a pouch having a non-uniform thickness. . Thereby, dissolution of the water-soluble sachet of the present specification can be controlled.

  Preferably, the sachet has a thickness variation of 10% to 1000%, preferably 20% to 600%, or even 40% to 500% or even 60% to a sachet formed of a stretched water-soluble film. Stretched to 400%. This can be measured in any way, for example using a suitable micrometer. Preferably the sachet is made from a stretched water-soluble film, the film having a degree of stretch of 40% to 500%, preferably 40% to 200%.

  The film preferably has a thickness of 1 μm to 200 μm, more preferably 15 μm to 150 μm, and even more preferably 30 μm to 100 μm.

  Preferably, the fabric treatment composition is a composition that is delivered to water, so the sachets and their compartments are designed such that the contents are released when the sachets are placed in water or shortly thereafter. . Therefore, the sachet having compartments is preferably formed of a water-soluble material. In one preferred embodiment, the component is released into the water within 3 minutes, more preferably within 2 minutes, or even within 1 minute after contact of the water with the sachet composition.

  In general, sachets can be made from any material suitable for use in conventional unit dose laundry products. However, it has been found that certain polymers and / or copolymers and / or their derivatives are preferred.

  Mixtures of polymers can also be used. This can be particularly beneficial in controlling the mechanical and / or dissolution characteristics of the compartment or sachet, depending on the application and essential requirements of the compartment or sachet. For example, it may be preferred that a mixture of polymers be present in the material of the sachet compartment so that one polymer substance has a higher water solubility than the other polymer substance and / or one polymer substance is the other. It has a higher mechanical strength than the polymeric material. Mixtures of polymers having different weight average molecular weights, for example, 10,000 to 40,000, preferably about 20,000 weight average molecular weight PVA or copolymers thereof, and about 100,000 to 300,000, preferably Preferably use a mixture of PVA with a weight average molecular weight of approximately 150,000 or copolymers thereof.

Can cause atomic substitution by.

  It is customary to distinguish clay based on a single cation that is predominantly or exclusively absorbed. For example, sodium clay is mostly sodium absorbed cations. Such absorbed cations can become involved in an equilibrium exchange reaction with cations present in the aqueous solution. In such an equilibrium reaction, it is customary, for example, that one equivalent of solution cation replaces one equivalent of sodium and the clay cation exchange capacity is measured as milliequivalents per 100 g of clay (meq / 100 g).

  The cation exchange capacity of clay can be measured by several methods, including exchange with ammonium ions, subsequent titration, or electrodialysis with the methylene blue method, all by Grimshaw, “Clay chemistry and physics ( The Chemistry and Physics of Clays), pages 264-265 (1971) of Interscience Publiser, Inc. The cation exchange capacity of clay minerals is related to factors such as the expandable properties of the clay, in other words, the charge of the clay determined at least in part by the lattice structure. The ion exchange capacity of the clay is in the range of 2 meq / kaolinite 100 g to 150 meq / 100 g, and the specific clay of the montmorillonite species varies widely within a larger range. The illite clay has an average ion exchange capacity of 100 g in the lower part of the range, ie approximately 26 mew / illite clay.

  Illite and carolinite clays, together with their relatively low ion exchange capacity, have been determined not to be useful in the fabric softening system of the fabric treatment composition of the present invention. In fact, such illite and carolinite clays constitute the major component of clay soils. However, nontronites having an ion exchange capacity of approximately 50 meq / 100 g; smectites such as saponites having an ion exchange capacity of greater than 70 meq / 100 g are useful fabrics in the fabric softening system of the fabric treatment composition of the present invention. It was found to be a softening active substance.

  All smectite clays conventionally used for this method herein are commercially available. Examples of such clays include montmorillonite, bolconskite, nontronite, hectorite, panonite, sauconite, and vermicrite.

(Skokie, Illinois); Black Hill from International Minerals and Chemicals • Benthite (Black Hills Bentonite) BH450; T.A. It is available under various trademarks such as Veegum PRO and Veegum F from Vanderbuilt. It should be recognized that such smectite-type minerals obtained under the aforementioned trade names and trademarks can include mixtures of the presence of various distinct minerals. Such a mixture of smectite minerals is suitable for use herein.

  Preferred for use herein are montmorillonite clays having an ion exchange capacity of 50-100 meq / 10 g, corresponding to a layer charge of about 0.2-0.6.

^{_{[(Mg 3-x Li x}} ) Si 4-y Me III y O 10 (OH 2-z F z)] - (x + y) (x + y) / nM n +
Where Me ^III is Al, Fe, or B; or y = 0; M ^{n +} is a monovalent (n = 1) or divalent (n = 2) metal ion, for example , Na, K, Mg, Ca, Sr, and mixtures thereof. In the above formula, the value of (x + y) is the layer charge of hectorite clay. Such hectorite clays are preferably selected based on their layer charge characteristics, i.e. at least 50% is in the range of 0.23 to 0.31. Further preferred are naturally derived hectorite clays having a layer charge distribution in which at least 65% is in the range of 0.23 to 0.31.

  While organophilic smectite clays provide an excellent softening effect, they can increase the viscosity of the liquid composition. Thus, how much of these organophilic clays can be used depends on the viscosity requirements of the composition.

  These organophilic clays are formed prior to incorporation into the detergent composition. Thus, for example, conventional smectite clay cations, or portions thereof, may be substituted with long chain organic cations prior to further processing the material to form the detergents of the present invention, and the organophilic smectites described herein.

Clays are well known in the art for their fabric softening performance. In general, clays are usually processed as aqueous suspensions. However, the use of aqueous suspensions of fabric softening clays is not allowed when the final composition is surrounded by water-soluble sachets because the moisture present is premature and therefore unnecessary Such as dissolution of the sachet material, i.e., at least partially before the consumer places the sachet in the washing machine, thus losing the treatment composition available in the cleaning cycle and / or It is because it will become dirty. In order to overcome this technical problem, the present invention proposes to add clays as a premix. These premixes comprise clay and a solvent, preferably a non-aqueous solvent.
